Foam is the most widely used material in vehicle cushions due to its low cost, lightweight, and shock-absorbing properties. It is also easily moldable, making it suitable for various cushion shapes and sizes. The most commonly used foam types include polyurethane, memory foam, and latex foam.

Polyurethane foam is the most popular choice for car cushions due to its high density, durability, and ability to retain its shape. However, it can be quite firm, so adding a layer of softer foam or padding on top can enhance its comfort properties.

Memory foam, also known as viscoelastic foam, is another popular choice for vehicle cushions. It molds to the shape of the body, providing excellent support and pressure relief. However, it can be quite dense, making it less breathable and prone to trapping body heat.

Latex foam is known for its excellent support, comfort, and durability. It is also naturally hypoallergenic and resistant to mold, mildew, and dust mites. However, it can be quite expensive compared to other foam types.

Gel cushions:

Gel cushions are made of a gel-like material that molds to the shape of the body, providing excellent pressure relief and support. They are commonly used in wheelchair cushions and are gaining popularity in vehicle cushions as well. The gel helps distribute weight evenly, reducing pressure points and promoting better blood flow.

Gel cushions also have cooling properties, making them an excellent choice for those who tend to get hot and sweaty while sitting for prolonged periods. However, they can be quite heavy and may not be suitable for all types of vehicles.

Air cushions:

Air cushions are made of inflatable materials and provide even weight distribution and pressure relief by adjusting to the shape of the body. They are highly customizable, allowing users to adjust the firmness and height to their liking.
